CHARLES M. HEETER, or BUTLER, PENNSYLVANIA.

SAMSON-POST AND Rio-neon To all whom 2'2, may concern:

Be it known that I, CHARLES M. HEETER, a citizen of the United States,and resident of Butler, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements inSamson-Posts and Rig-Irons, of which the following is a specification.

The object of this invention is to provide an improved samson post whichis designed especially for an under-slung walking beam, 2'. 6., a beamjournaled at the upper side instead of in the more usual location at thelower side. This arrangement necessitates the provision of sutficientspace between and beneath the hearings to accommodate the walking beam,also suitable means for supporting the separated bearings. In thepresent invention due regard is had for these requirements withoutinterfering with the necessary substantial construction, andparticularly with regard to solidly mounting the samson post on the mainsill. This sill is in efiect the back bone of the rig ground work. Itextends well outwardly from the derrick and rests on several cross sillsor ties, the latter also serving to suport the band wheel and otherassociated parts. The main sill holds the several parts in alinementwith each other and with the Well, whereby the walking beam ismaintained in proper position relatively to the well. \Vith the presentinvention, the substantial mounting of the samson ost on the main sillis not interfered with, the construction in this regard not beingessentially different from the usual practice.

In the accompanying drawings, Figure l is a side elevation of a portionof a well rig with the improved samson post in position therein. Fig. :2is a sectional elevation of the samson post taken at right angles to theposition in which it is shown in Fig. 1. Fig. 3 is a vertical sectiontaken on line 33 of Fig. 2. Fig. 4 is a view of the samson post andwalking beam shown partly in top plan and partly in sectional plan.

Fig. 5 is a detail view of one of the guides.

Referring to the drawings, 2 designates the main sill of a well rigwhich is mounted on cross ties 3 and derrick sill 4:, the latterconstituting a support for two of the derrick corner posts 5, one of thelatter being broken away in Fig. 1 to avoid obscuring the samson post.The main sill extends well beneath the derrick floor 6 as shown.

-' The samson post consists of two uprights 7 having their lower endstied together by bolt 8 and in engagement with each other and with thelower extremity of the twopart'post mortised in the main sill asindicated at .9. This is the usual manner head 11 which is flangeddownwardly on its outer side at 12 and apertured for bolting to upright7, and extending upwardly from the head and spaced outwardly from thebearing socket 13 is the upstanding arm 14, the position of said armresulting in the formation of a space 15 between it and the upperportion of block 11. Above the beam the two arms 14 are secured togetherby the transverse tie-rod 16.

The beam is suspended in the'space between the upper ends of uprights 7on trans verse shaft 17, being secured thereto by the U-shaped bolts 18and the clamping plate 19. The projecting portions of shaft 17 atopposite sides of the beam form trunnions 20 which bear in sockets 13 ofheads 11, and at the extremities of the trunnions are the knob-likeenlargements 21 which project into spaces 15, and with the bearing caps13 in place the knobs on the trunnion extremities provide for tyingtogether the bearings, thereby further reinforcing the two-part postagainst spreading. This I transverse reinforcement in addition to tierod16, also transverses bolts 22 and block 23 beneath the beam, provide apost that is quite as strong as though made of a single heavy timber,and at the, same time the mounting of the two-part post on the main sillis not different from the single-timber construction.

The advantages of the invention will be readily apparent to thoseskilled in the art. Qwing to the scarcity of timber, the two uprights 7each of smaller dimensions than the usual single timber cost materiallyless than the latter, and the under-slung mount: ing for the walkingbeam permits of the use of a much shorter beam than when the beam isjournaled at its under side, this being due to the fact that with thejournal at the top of the beam the deflection of the tool orpump-actuating beam extremity 10 is comparatively slight in movingeither upward or downward, far less than it would be if it wereattempted to fulcrum so short a beam at its under side, the result beingthat when drilling, the lateral deflection of cable 2% is not suflicientto cause it to wear unduly as a result of its engagement with standpipe25 of the well. The shortening of the beam results in setting the samsonpost closer to the derrick, thereby shortening the main sill and makingthe ground framework more compact.

I claim:

1. The combination with a samson post consisting of two uprights spacedapart at their upper ends, of alined bearings secured to. the uprightsand consisting of heads resting on the extremities thereof and providedwith journal seats, flanges depending from the heads and secured to theuprights, and journals for a walking beam rotatable in said seats.

2. The combination with a samson post consisting of two uprights spacedapart at their upper ends, of alined bearings secured to the uprightsand consisting of heads resting on the extremities thereof and providedwith journal seats, flanges projecting upwardly from the heads, walkingbeam journals mounted in said seats, and a tie-rod above and parallelingsaid journals and connecting said upwardly extending flanges.

3. The combination with a samson post consisting of two uprights spacedapart at their upper ends, of alined bearings secured to the uprightsand consisting of heads resting on the extremities thereof and providedwith journal seats, flanges extending upwardly from the outer sides ofthe heads, the anges spaced outwardly from the seats, walking beamjournals mounted in the seats and having knob-like extremities extendinginto th spaces between the seats and the upwardly extending flanges, anda tie rod above and paralleling the journals and secured to the upwardlyextending flanges.

l. The combination with a Samson post consisting of two uprights spacedapart at their upper ends, of alined bearings mounted on the uprights, awalking beam journal shaft mounted in the bearings, and enlargements onthe extremities of the shaft engaging the outer sides of the bearings,whereby the shaft comprises a tie for holding the bearings fromspreading apart.

5. The combination of the main sill of a well rig, a samson postconsisting of two upright-s secured together at their lower ends andmounted on the main sill as one post, separating means between saiduprights intermediate of their ends, forming spaced apart upper ends ofsaid uprights, bearings secured to the separated upper ends of theuprights, connecting means for said separated upper ends of saiduprights, a walking beam adapted to oscillate between said uprights, andtrunnions projecting from the walking beam and mounted in said bearings.

G. The combination of a well rig including the main sill forming aportion of the rig foundation and projecting outwardly therefrom, of asamson post consisting of two uprights spaced apart at their upper endsto receive separated walking beam bearings, said uprights convergingbelow said spaced apartupper ends and secured together to form a unitarypost at their lower ends, said unitary post resting on and secured tothe main sill.

In testimony whereof I affix my signature in presence of two witnesses.
